+1 specifically, try removing the space after the "=" in all 3 lines: A=`cat ...` B=`expr ...` C=`expr ...` and there may also be a problem with the spaces in the "expr" lines. You should be able to try each command on the command line, including the 'A=' part until you have the syntax correct, then the script should also work.
